If you’re craving an adventure that combines cave exploration, jungle trekking, and authentic local culture, the Dong Hoi Expedition to Cha Loi Cave is a fantastic choice. For just $79 per person, you’ll spend about 8 hours immersed in the natural wonders and historical gems of central Vietnam, visiting lesser-known caves, crossing rivers, and feeling like a real explorer. A local guide will lead you through the journey, making sure you get the most out of the experience.
What we love about this tour is the variety of activities, from walking and crawling through narrow passages to swimming in underground streams—perfect for thrill-seekers.

The Itinerary in Detail

Starting in the early morning, your adventure begins with pickup from your hotel in Phong Nha (or Dong Hoi if you specify). We appreciated the prompt and friendly service, with a comfortable ride as the guide shares snippets of local history, like the significance of the Long Dai ferry during the Vietnam War. The crossing over the Long Dai Bridge offers a great photo opportunity and a glimpse into Vietnam’s past—highlighting the tour’s blend of natural beauty and historical depth.
Next, you’ll arrive at Sung village, where you’ll receive all the gear needed for the cave adventures, including flashlights, shoes, and gloves. The guide will show you how to use this equipment—an important step to ensure safety and confidence. We liked how the guide explained the principles of cave exploration, making us feel prepared for what’s ahead.

Visiting Hang Nuoc (Ong Giap) Cave
Before heading to Cha Loi, you’ll explore Hang Nuoc, or Ong Giap Cave. This spot is special because of its unique features—stalactites, water passages, and a sense of adventure. It’s a quieter, less touristy cave that gives you a taste of what’s to come at Cha Loi. The highlight here is the feeling of walking through a less-traveled but equally fascinating cave system, setting the tone for the larger adventure.
Discovering the historical A72 Station
After Hang Nuoc, the journey continues to the A72 information station, which played a key role in Vietnam’s military communications from 1971 to 1973. Visiting this site adds a historical dimension, reminding us of the region’s past conflicts and resilience. It’s a quiet moment to reflect amidst the rugged scenery.
The Main Event: Cha Loi Cave
The heart of the tour is the over 4 km of cave exploration within Cha Loi—truly a highlight. Here, you’ll walk, crawl, climb, and swim through a series of interconnected chambers, tunnels, and water-filled passages. The landscape inside is spectacular: towering stalactites, beautiful formations, and narrow tunnels that demand a bit of agility and curiosity.
Many visitors, like Lorenzo, noted the “beautiful crossing in a cave with many concretions and water passages”. The experience is enhanced by the chance to capture stunning photos of the cave’s natural sculptures, especially the famed “Tunnel of Love,” which offers a particularly picturesque moment. The tour is designed to be engaging, and our guide made sure everyone stayed safe while enjoying the thrill.

The meal is included, and the food reflects the area’s authentic flavors, providing a well-earned break. Then, a visit to Coi village offers a chance to see the Van Kieu people’s Love Valley, adding a cultural element to the day.

Return and Reflection
The return trip includes a scenic drive and a relaxed vibe, with the group sharing stories and photos. The tour wraps up around 5:30 pm, leaving you with plenty of memories—and maybe a sore arm from all those cave photos!
What Makes This Tour Stand Out

One of the key strengths of this experience is the combination of adventure and history. Unlike many standard cave trips, the visit to the A72 station and the historical context enriches the experience, making it meaningful as well as exciting. The variety of activities—walking, climbing, swimming—keeps the energy high and the boredom low.
Another highlight is the authentic local interaction. Visiting Coi village, enjoying traditional food, and seeing the region’s lesser-known sites offer a more genuine connection to Vietnam than the typical tourist trail.
The well-organized logistics—timely pickups, safety briefings, provided gear—reduce stress and let you focus on the fun. The small group size (not specified but implied to be manageable) ensures that you get personal attention and a tailored experience.
The Value of the Experience

At $79, this tour offers a lot of bang for your buck. It includes round-trip transportation, all necessary gear, a local guide, meals, and a meaningful cultural element. When you consider the physical effort involved and the exclusive access to less-visited caves, the price feels justified, especially given the quality of the adventure and the depth of historical context.
It’s especially good for active travelers who appreciate a mix of physical challenge, stunning scenery, and cultural insight. The tour is not suitable for children under 8 or people with certain health conditions, but for those who are fit and eager to explore, it’s a memorable day.
